Configure SAML single sign-on with Okta

You can configure your ExtraHop system to enable users to log in to the system through the Okta identity management service.

Before you begin

  • You should be familiar with administrating Okta. These procedures are based on the Okta Classic UI. If you are configuring Okta through the Developer Console, the procedure might be slightly different.
  • You should be familiar with administrating ExtraHop systems.

These procedures require you to copy and paste information between the ExtraHop Admin UI and the Okta Classic UI, so it is helpful to have each UI open side-by-side.

Enable SAML on the ExtraHop system

  1. Log in to the Administration page on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Access Settings section, click Remote Authentication.
  3. From the Remote authentication method drop-down list, select SAML.
  4. Click Continue.
  5. Click View SP Metadata. You will need to copy the ACS URL and Entity ID to paste into the Okta configuration in the next procedure.

Configure SAML settings in Okta

This procedure requires you to copy and paste information between the ExtraHop Admin UI and the Okta Classic UI, so it is helpful to have each UI open side-by-side.

  1. Log in to Okta.
  2. In the upper-right corner of the page, change the view from Developer Console to Classic UI.
  3. From the top menu, click Applications.
  4. Click Add Application.
  5. Click Create New App.
  6. From the Platform drop-down list, select Web.
  7. For the Sign on method, select SAML 2.0.
  8. Click Create.
  9. In the General Settings section, type a unique name in the App name field to identify the ExtraHop system.
  10. (Optional): Configure the App logo and App visibility fields as required for your environment.
  11. Click Next.
  12. In the SAML Settings sections, paste the Assertion Consumer Service (ACS) URL from the ExtraHop system into the Single sign on URL field in Okta.
    Note:You might need to manually edit the ACS URL if the URL contains an unreachable hostname, such as the default appliance hostname "extrahop". We recommend that you specify the fully qualified domain name for the ExtraHop appliance in the URL.
  13. Paste the SP Entity ID from the ExtraHop system into the Audience URI (SP Entity ID) field in Okta.
  14. From the Name ID format drop-down list, select Persistent.
  15. From the Application username drop-down list, select a username format.
  16. In the Attribute Statements section, add the following statements exactly as shown. The first four attributes are required. The user.packetsLevel and user.detectionsAccessLevel attributes are optional. If you have a Trace appliance and you do not configure the user.packetsLevel attribute, users will be unable to view or download packet captures in the ExtraHop Web UI.
    Name Name format Value
    urn:oid:0.9.2342.19200300.100.1.3 URI Reference user.email
    urn:oid:2.5.4.4 URI Reference user.lastName
    urn:oid:2.5.4.42 URI Reference user.firstName
    urn:extrahop:saml:2.0:writelevel URI Reference user.writeLevel
    urn:extrahop:saml:2.0:packetslevel URI Reference user.packetsLevel
    urn:extrahop:saml:2.0:detectionsaccesslevel URI Reference user.detectionsAccessLevel

    The following figure shows a completed example.



  17. Click Next and then click Finish.
    You are returned to the Sign On settings page.
  18. In the Settings section, click View Setup Instructions.
    A new browser window opens and displays information that is required to configure the ExtraHop system.

Add identity provider information on the ExtraHop system

  1. Return to the Admin UI on the ExtraHop system. Close the Service Provider metadata window if it is still open, and then click Add Identity Provider.
  2. Type a unique name in the Provider Name field. This name appears on the ExtraHop system login page.


  3. From Okta, copy the Identity provider single sign-on URL and paste into the SSO URL field on the ExtraHop system.
  4. From Okta, copy the Identity Provider Issuer URL and paste into the Entity ID field on the ExtraHop system.
  5. From Okta, copy the X.509 certificate and paste into the Signing Certificate field on the ExtraHop system.
  6. Choose how you would like to provision users from one of the following options.
    • Select Auto-provision users to create a new remote SAML user account on the ExtraHop system when the user first logs in to the appliance.
    • Clear the Auto-provision users checkbox and manually configure new remote users through the ExtraHop Admin UI or REST API. Access and privilege levels are determined by the user configuration in Okta.
  7. The Enable this identity provider option is selected by default and allows users to log in to the ExtraHop system. To prevent users from logging in, clear the checkbox.
  8. Click Save.
  9. Save the Running Config.

Configure user privilege attributes in Okta

You must add ExtraHop privilege attributes to Okta. These attributes enable you to assign write-level, detections-level, and packet-level access to your Okta users. You only need to configure user privilege attributes once in your Okta environment. These attributes can then be assigned to any Okta user profile.

The Detections Access Level attribute is only required when the global privilege policy is set to Only specified users can view detections.
  1. From the Data type drop-down menu, select string.
  2. In the Display name field, type Detections Access Level.
  3. In the Variable name field, type user.detectionsAccessLevel.
  4. Click Save and Add Another.

Configure packet access
